There are many free Treasures materials I use out there made by teachers to go with the Treasures series. Of course I don't always use the Basal. I like to supplement lots of other things, but our school still likes us to use it.
If you haven't found Mrs. Winston's Trifolds they are awesome. She has one for every story in the basal and also lots of other books too. (Magic Tree House, Cam Jansen books, Jigsaw Jones, etc.) Be sure to download and try them out. They are great for Reading Comprehension strategies.
Mrs. Shaw's website has vocabulary power points made for every story.
And Treasures for Teachers has nice vocabulary match up with definition cards.
And my favorite Mrs. Ziruolo's Jeopardy Games. They review all the skills for the week from the story. My students love playing this game as a weekly review.
These are all for the Second Grade Stories and hope all you Second Grade Teachers who have the Treasures series find these as helpful as I have.
